Dataquest

Since I decided to change my career heading to be a data scientist, I realized how important is having a constant learning routine. Therefore, at least once a week I spend some hours getting new knowledge. Among several platforms that I have been using... Read More lately, Dataquest is one of the best. The way topics are organized through amazing "missions" helps a lot the way I learn. Everything is well planned and it is wonderful how I notice my progress. Not to mention the very thoughtful support!
I really recommend Dataquest!

I have been using DataQuest for only a couple of months and, in that time, it has been nothing short of wonderful. I am on the Data Scientist path and learning with Python. Here is why the program is amazing:

- The missions are streamlined and not bogged... Read More down in too much unnecessary information. It is to the point for the mission at hand. There is never any fear of turning away out of boredom because you are moving effortlessly and efficiently from mission to mission, learning and absorbing so much along the way.
- The missions use real-life data. It is like you are already a data scientist, in a way, just by working through the missions. And by using the real-life data, you are able to understand how and why Python works so well in analyzing the data. One might be turned off from learning Python in a vacuum. In realizing its applications right out of the gate, though, the material as presented is intriguing and fun. One never becomes bored.
- The interface is also quite effective and accessible. The text is on the left and the terminal/notebook on the right. No worries if you have trouble accessing a terminal and/or notebook because the service provides both.
- You have the option to practice bits of code before submitting them for a solution. This makes all the difference because you always have the option of answering any lingering questions you may have by quickly checking the code in the terminal. And after you submit the code as a solution, the program tells you if you are right or wrong and does not allow you to proceed until the code is correct. So you keep practicing until you understand and arrive at the right solution, which never takes too long. If you do get stuck, the solution is available. But with the practice in the terminal, looking at the solution before submitting your answer is never necessary.
- As you complete various missions, you are rewarded with certificates, which only further motivates you to want to continue in learning more.
- There is a community forum that allows you to ask any questions you may have. And the staff at DataQuest is also available for those questions. You never have to worry about getting stuck anywhere. People are always around to assist.

The service is perfect in every way!

Before I know dataquest, I learned to code via videos online or books.But they are just not efficient ways for me to learn so I searched for interactive website.I don't know if Dataquest is the best website for people who wanna be good at data sicence,but... Read More I can tell it suits me most so far.Beautiful interface , powerful teaching theory with deliberate practice and there are many data scientist will reply your question as long as you send them a message.I am still keeping going on dataquest and I am real user from China.I think it's wonderful so I recommend it for all of you who wanna join in data science but has no idea how to begin.At last I wanna thank the team who built dataquest, you are must really wise people.

Pros:
- Good introduction to beginners, does not go too in depth into each topic, just enough for further self study.
- Links to documentation are convenient.
- Explanation is layman, convenient to go back and re-read compared to video lessons
- Interface... Read More is user friendly. Split-screen learn and do allows application immediately
- Concepts are broken into small chunks and linked
- Free content is plenty.
- Slack community is rich with discussion, better than getting ignored on stackoverflow
- Self-paced

Cons:
- Programming in browser will not generate as much warnings as in local environment using Jupyter notebook, thus not maximizing learning
- Forums for free missions have limited answers to questions
- Usually only 1 way of doing things/ 1 library function introduced at each step in the missions (not the guided projects though)

JOB SUPPORT 3 star because have not experienced it yet.

Conclusion: Just try it for 10 minutes (it's easy to set up) and see if it fits your mode of learning.

I have tried lots and lots of MOOCs in the fields of data science and machine learning. Guys trust me. If you really want to learn the domain, go for dataquest.io! Most of the courses are scratching the surface only by discussing high-level theory. Even... Read More if there is a code shown, you won't get the practice and confidence in coding (scripting). Other courses are focusing on tools and coding without diving deep into the theory.
Dataquest is the only comprehensive offering I am aware of. And what makes it so outstanding? Simple:
1. It is extremely well structured. Your knowledge will be built up step by step using learning by doing approach. Both your technical skills and theoretical knowledge will evolve hand in hand.
2. It goes under the hood. You will really understand the details, you will really know what is happening and why. E.g. Wherever it is possible you will write the machine learning algorithm from scratch before you start using the pre-built package. Does it take time? Yes. Does it worth it? No question about it!
3. The content evolves continuously. Let's face it, this domain is so hot that it changes rapidly. Tools are improving, new methods appear etc. And as I experienced it, Dataquest stays on top.
4. You will master both theory and practice and you will end up with your own portfolio

DataQuest is the best platform I have come across for learning data science. The biggest selling point for me was the wide range of topics available, as evidenced by the three paths available: data scientist, data scientist, engineer and analyst. This... Read More means you will not need to scour the web to puzzle together a collection of resources to teach you what you need to know: it's all just there.

The platform is a joy to use, and I have not encountered any major bugs whatsoever. It is also constantly updated, and very intuitive to use. For those of you on the fence, give it a try. With this platform, the only obstacle to mastering data science is how much time you have to learn it!

Pros
Best bang for your buck. Each course offers a certificate along with the overall course path: data engineer, data analyst, and data scientist.

Gives a course on how to use Kaggle with background in the mathematics of data science.

All the courses are... Read More in text, so doing it at work without headphones is very convenient.

The help during learning how to code is not penalized and positive reinforcement is given throughout the learning path.

Cons
Some errors in the code, but very small. Also there are some projects that do not have solutions.

This might matter to some, but, I found it as a pro, no videos.

Job Support
They have a job support for the highest form of membership. I gave them 3 starts, since I did not attend the highest form of membership but the premium program alone offers a great portfolio alone. People that are already familiar with job hunting will thrive in finding a data science job without the extra support.

Overall
Great course. If I only had to chose 1 site to learn data science, then it would be this site. I like to use their competitors as supplementary material. I find Dataquest's lessons to be clear in describing concepts into practice.

Pros:
1. Highly structured course that takes someone with absolutely no experience in programming to professional standards in Data science fairly quickly.
2. Many guided projects available that helps you build a strong portfolio to impress employers
3.... Read More Subscription fee kicks in only after your done with the first few courses so you can decide whether to go ahead with the program or not
4. Concepts are mentioned clearly and approached in a practical manner
Cons:
1. There are a few bugs in some parts of the course (<1%)
There really isnt any cons for me to list out, Dataquest has been a very good supplement to add to my Data science portfolio

Compared to other data science course providers, Dataquest has content is really good, offers guided projects and easy way of teaching stuffs.Courses are well structured and community is also good. Python courses are well structured and advance courses... Read More offered on the same are really worth for the money.

I have many years of experience on computer science. After a master's degree and a job as an IT analyst, I wanted a change. So I decided to be a Data Scientist!

I chose Dataquest because of:
- the quality/price ratio is satisfying
- it covers all the basic... Read More topics to start a career in Data Science
- the community on slack is very active and you can team up with a lot of people there
- some steps need still to be improved since the explanation is not clear, but overall I'm glad to study here

Also, I have experience on computer science already, but people who are switching for the first time to it seem happy to be part of the community.
